APPROPRIATION / PHASE: Continuing Authorities / Feasibility

BUSINESS PROGRAM: Flood Damage Reduction

AUTHORITY: The authority for this project is Section 205 of the Flood Control Act of 1948 (Public Law 80-858), as amended. Under this authority, the USACE is authorized to plan, design, and construct small flood damage reduction projects. Each project is limited to a Federal cost of not more than $10 million, including all project‑related costs for feasibility studies, planning, engineering, design, and construction.

DESCRIPTION: The focus of this feasibility study is the lower reach of the Assunpink and its tributaries that are located in the City of Trenton, Hamilton Township, and Lawrence Township, New Jersey. Within the study area, flooding problems are widespread. The wide floodplains of the relatively low gradient streams are subject to chronic flooding and, on several occasions, extensive flood damage has occurred.  Most recently, the study area experienced record flood levels and a great deal of property damage as a result of the heavy rains brought by Hurricane Irene in August of 2011.   Flooding on the Assunpink Creek that resulted from Hurricane Irene shut down the rail lines in the City of Trenton for three days.  This disrupted one of the busiest parts of the nation’s passenger train system between Philadelphia and New York.  This feasibility study is examining the flooding problems along the Assunpink Creek and evaluating the Federal interest in implementing flood risk management solutions.

PROJECT GOALS: The purpose of this project is to examine potential solutions to reduce frequent flooding problems.

STATUS: The USACE executed a Feasibility Cost Share Agreement (FCSA) with the New Jersey Department of Environmental Protection (NJDEP) in FY 2014.  The non-Federal sponsor is responsible for 50 percent of the costs of the Assunpink Creek Flood Risk Management Feasibility Study. The NJDEP is developing hydraulic modeling to support the technical analyses as part of their required costs share match. 

SPONSOR: New Jersey Department of Environmental Protection
